<p>A projection system comprises a plurality of reflective LCDs (41, 42, 43) which are irradiated with colored sub-beams (21, 22, 23). The sub-beams are not perpendicularly indicent on the LCDs so that the reflected beams (24, 25, 26) do not coincide with the incident beams. The sub-beams originate from a white light beam (20) which is split up into colored sub-beams by means of color-selective mirrors (31, 33). The same mirrors are used to combine the reflected beams (24, 25, 26) to a projection beam (27). An angle-dependent beam separater (80) is arranged so as to realise a spatial separation between the incident beams and the reflected beam. The angle-dependent beam separater (80) is arranged in such a way that the angle at which the beam (20) is incident on the color-selective mirrors (31, 33) is equal to the angle at which the reflected sub-beams (24, 25, 26) are incident on these mirrors.</p> |
